Receivers and Audio Components

I am looking for a TV speaker that I can place on a table near a chair of a hearing impared person. I want a speaker that has a volume control and is small in size. I would need a long wire to reach around the room. My TV is a standard TV with a red and yellow input jack. I still want sound to come from the main TV when the speaker is on so other people can also hear the TV.
I have asked several web sites and they either say there is no such thing or I need buy a receiver first. Any help would be appreciated. Thank you

Hi,

I need help with respect to Bose system. I purchased Bose Acoustimass 16 a few days back. I connected it through Onkyo A/V reciver. After a day, the subwoofer system gave out a rumbling sound and quit working. The Bose guys asked me to get it exchanged and I recived a 2nd piece. The same thing happened to the 2nd piece too. Now the 3rd one is on its way.

I am unable to understand the reason for it to fail like this.

I need to move a pair of speakers across the room from my receiver but have limitations on speaker wires. Because of broken up walls with which I have to work ( windows & doors ), my only option it to run wires at the top of the walls then down to speakers. To me this isn';t an option. What, if anything, can I get to make these speakers wireless without ruining their sound.
